Sparkle Fan
by
Tino Kreiss
The idea behind the Calibre cooler is two fans that can be expanded like wings. Aside from the cool looking aesthetic component, we could not measure any difference with our open test platform, though. In 2D applications, the temperature measured 44 °C, while under 3D permanent load it reached 66 °C. The measured temperatures and the noise level of 36.3 dB(A) remain constant, whether the fan was folded or expanded and whether the card was under load or idle.

"Under permanent load we measured temperatures of up to 103 °C"
Not what you would call fit for purpose as a GPU, unless is also marked as a space heater!.
Why don't we have any ATI 4670 ? reviews or comparisons or benchmarks ? Who is interested in the Green cards anymore ? Especially when the conclusion is, buy another model green card. Seriously is this site sponsered by Nvidia ?
where's the GTX280 and the 9800GX2???
Blimey, I'm surprised my 8800GT compares so well with that list (SM2.0
of 5457, SM3.0 of 5704, overall score 11762 (CPU limits the overall
scores as it's only an AMD 6000+). toms must be using a pretty naffy
8800GT to only get an SM3.0 of 4984 (oh yeah, just stock clocks -
who the heck buys that these days?), especially given the X6800 being
used is 25% faster than mine. Speaking of which, if one is going to
bother testing with games like Crysis, why only use a dual-core? Surely
it makes sense to use a good quad-core so that one can be sure higher
resolution tests are not limited by CPU issues?
Overall, just more proof that the naming scheme for the 9xxx series was
crazy. Why does NVIDIA keep releasing so many different overlapping
variants with names that make no sense? The number of different names
is laughable.
Re other cards like the GTX280: maybe they haven't included more since
one can always infer other comparisons based on the various VGA charts.
The only thing I wish they'd stop doing is using MS FSX which is really
badly written (suffers terrible slowdown without the full PCIe speed
as it reloads textures constantly).
Also, has anyone ever done an analysis of exactly what Crysis is doing?
Sites are so fond of using it as if it's the ultimate benchmark because
it hammers gfx cards so hard, but how do we know it's not just
inefficiently written instead? No way to tell. How many polys per frame
typically? Not seen this mentioned anywhere. I did send this question to
NVIDIA but nobody replied. I think I would have more respect for Crysis
performance results if I could be sure it was getting more out of the
cards compared to other games, but I have to say the movie demos I've
seen don't look that good compared to, say, Stalker Clear Sky which
is said to have over a million polys/frame (a rather rough measure to
be sure, but better than nothing).

I was sold on this unit until I read that. I really don't understand why some RAM sinks couldn't be used. As a consumer I really don't want to be looking at the temps all the time wondering if the chips are going to overheat.
